Re: [Boost-users] [function] vs2005 warning

I'd like to chime in to increase the strength of the voice - I also get lots
of warnings from boost which I'd like to remove, in order to see the forest
for the trees.  In my case, it is typically boost placeholders - _1, _2,
_3,... and the warning is about unused globals.

Is there a way we can get fixes for these and reduce the warnings coming
from boost?
